`In the construction of dust mops and particularly the type of mop in which the swab may be .removed by the user Whenever desired, considerable Ainconvenience and diiiiculty has been experienced in vthe application of the supporting structure Yfor the swab to the handle. The present invention provides 'a simple and .practical device in which the swab may be readily and Veasily applied to or remo-ved from the mop.

For the purpose of illustrating the application of'my invention I have shown in Fig. 1 a handle 'lil which may be constructed of wood'or any other suitable material. The said handle is preferably round and is formed with a tapered end II to which the swab of the mop is attached.

The inp Aproper consists of a swab holder I2 which is `constructed from spring Wire coiled to 'provide a number of convolutions 26 which form a coil spring indicated in its entirety by the reference numeral I3. This coil spring is adapted "to be ybent Vinto a loop as shown in Fig. 1 'and is attached IVto vthe handle l0 as will be presently described in detail. The swab, not shown in the drawings, is constructed with a hem or similar construction through which the said coil spring is inserted and by means of which the swab is attached to the holder. Inasmuch as the swab does not form any particular feature of the invention, the same has not been shown in the drawings, though it can readily be comprehended that any construction, such as is now in common use and such as is disclosed in Patent No. 1,849,- 150, may be used for the purpose. The swab holder I 0 being constructed as a coil spring is flexible and permits of bending the swab to cause the same tofollow the contour of the surface on which it is applied and permits of readily manipulating the mop in crowded corners and in localities where a rigid holder could not be effectively used.

The swab holder is attached to a Supporting structure referred to by the reference character I4 which supporting structure consists of a support I5 formed of a cylindrical rod bent to provide two angularly disposed portions I6 and I1 which serve as shanks and a connecting portion I8 between the same. In the form of the invention shown in Figs. 1 to 4, the Shanks I6 and I1 are reduced in diameter as designated at I9 and 2| Upon the reduced portion 2I is mounted a head 22 which is bored at 23 to receive the same. This head is secured to the said reduced portion of the shank through a pin 24. The exterior of the head 22 is constructed with threads 25 which are adapted to Screw into the convolutions 2B of the coil spring I3. It can readily be comprehended that when the coil spring AI3 is free, one end 21 of the same may be screwed upon the head 22 and so held attached to the support I5.

For attaching the other end 28v of the coil spring I3 to the support I5, a construction is employed which is best shown in Fig. 3. Mounted upon the reduced end I9 of the shank I6 of the support is another head 29 which is free from the threads and whichis bored as indicated at 3I to iit over the same. This head is secured to the shank through a pin 32. The outer diameter of the head 29 is such that the same fits freely Within the interior of the coil spring I3, the same serving as a guide for guiding the coil spring for sliding movement into position upon the support I5. In conjunction with the head 29 a Sleeve 33 iS employed which isconstructed upon the interior thereof with threads 34 adapted to screw upon the exterior of the convolutions 26 of the end 28 of coil spring I3. This sleeve is further constructed with a flange 35 which is rotatably `mounted upon the shank I6 immediately in back of the head 29. The head 29 is slightly larger in diameter than the shank I6 to form a shoulder 31 adapted to be engaged by the ange 35. By means of this construction the sleeve 33 is rotatably supported on the Shank and the same held from axial movement in one direction. For restraining the sleeve 33 from axial movement in the opposite direction, a pin 38 is employed which passes through the shank I6 and is secured thereto and which engages the end of flange 35.V The outer Surface of the sleeve 33 is knurled as designated at 39 by means of which thegsame may be readily rotated by the user when it is desired to attach the end 28 of the coil spring to the swab holder. l

The supporting structure I4 further includes two attaching members 4I and 42. These two attaching members are provided with curved portions 43 and |43 which fit about the tapered end II of handle I0. Two rivets 44 and 45 pass through both of the members 4I and 42 and hold the same rigidly attached to the handle. The ends of the members 4I and 42 are bent to t about the connecting portion I8 of the support I5. For assisting in holding the said parts attached together, the member I5 is ilattened as designated at 46, whereby the ends 41 and 48 may be firmly seated upon ,the connecting portion I8. A rivet 49 passes through the portions 41 and 48 and also the connecting portion I8 of support I5, whereby the members 4I and 42 are rmly attached to the support. The end portions 5I and I5I of the attaching members 4I and 42 engage the outer surface of the connecting portion I8 of Support I5 and help to hold the Said support from lateral movement with respect to the attaching members 4I and 42.

Although I have described the members 4I as attached to the member I5 through a rivet, it can readily be comprehended that the two attaching members 4I and 42 may be Secured thereto in any other suitable manner.

In the description of the invention, a stationary threaded member has been Shown on one of the Shanks o-f the support, while a revoluble threaded member has been shown on the other.

The use of my invention is as follows: When the mops are sold the supporting structures I4 are attached to the handles Ill and. thefswab holders and swabs furnished Separate.Y When del coil spring inwardly into the interior vof said sleeve until the extreme end of the coil spring engages the flange 35. During such movement the coil spring is drawn over the head 29"'which together with the Sleeve 33 causes the said end of the coil spring to be firmly and securely held 'in position. The mop is now in position for use and may be used in the customary manner.

In Figs. 5 and 6 I have shown a modification of the invention. In this form of the invention two Supports 52 and 53 are provided'which are constructed with cylindrical Shanks 54 and 55. These Shanks are formed at their Vends with curved portions 56 and 51 which t over thetapered end II of handle I0. The two portions 56 and A51 are secured to the said handle through rivets 58 and 59 similar to the rivets 44 and 4 5 of the other form of the invention. The two Shanks 54 and 55 are constructed with reduced ends 6I and 62 which provide shoulders 63. Two sleeves 64 and 65 are revoluble upon the Said reduced portions of the Shanks 54 and 55 and are seated at one end against the Shoulders 63, being restrained from longitudinal movement toward lthe handle thereby. The other ends of the said sleeves are held from longitudinal movement in the opposite direction through heads 66 formed on the ends of the reduced portion 6I of said Shanks by riveting over the same. The sleeves 64 Vare `constructed with external threads 61 and vII51 which screw .into the interior of the coil interior thereof. The sleeve 64 is constructed with a flange 68 at the end thereof which ange is knurled on the exterior as designated at 69 to permit of readily rotating the same. By means of this construction, the threads 61 and |61 can be screwed into convolutions 26 of the spring I3 and the end of the spring attached to the support 52.

The use of the invention shown in Figs. 5 and 6 is similar to that previously described. One end of the spring I3 may be rst screwed upon one of the sleeves 64 or 65 and the swab then applied. The other sleeve is then rotated through the knurled ange 68 and screwed into the reduced end of the spring on which the swab is mounted causing the threads thereof to engage the convolutions of the other end of the spring.

My invention is highly advantageous in that an extremely simple and practical device is provided, whereby the ends of the coil spring used as a swab holder may be easily and securely attached to the supporting structure therefor. A swab holder attached through the means shown is readily applied and when once applied,

remains permanently in position until it becomes necessary to remove the swab from the swab holder. The application of the swab holder to the support is accomplished through simple Inanipulation such as is readily understood by any person capable of using the mop. The invention can be constructed at a nominal cost and by simple manufacturing methods. My invention is extremely rigid and substantial in construction and has all of the advantageous and desirable characteristics of similar mops constructed in other different ways.

Changes in the specic form of my invention, as herein disclosed, may be made within the scope of what is claimed without departing from the spirit of my invention.
